FOUNTAIN-PEN. FILLER.

Application filed March 23, 1923. Serial No. 627,191.

To all lwhom it may con-cern.'

Be it known that I, BENJAMIN L. DALL, a citizen of the United States, residing at rChicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Fountain-Pen Fillers, of which the following` is a specification.

This invention relates to a filler for foun tain pens and is fully Adescribed in the following specification 'and shown in the accompanying drawings in which;

Figure 1 is a longitudinal section through the link reservoir.

Fig. 2 is a'partial section of the same as applied to a fountain pen during the act of filling and Fig. 3 is a same View ofamodiied form of tube.

The embodiment illustrated consists of a tubular member 10 closed at one end and having a screw thread 11 formed in the opy posite end which may be adapted to fit the threads 12 of a fountain pen 13 which are commonly used for securing a captherein.

An outwardlyflaring circular shoulder 14 is secured within the tube 10 in such a position as to engage the circular end 15 of the fountain pen when the latter is screwed into the end of the tube.

The pen is provided with some form of self filling device such as an operating lever l 16 pivoted on a pin 17 and having a lower lend 18 adapted to press inwardly on a metal bar 19 which lies along the rubber tube 20. This is a well known form of self filling pen which is ordinarily filled by moving the lever 16 outwardly to dotted line position thereby collapsing the rubber tube '20, inserting the pen point into ink so that the lower end 15 is submerged and returning the lever 16 to full line position thereby permitting the collapsed tube 2O to expand and draw ink up filling the same. A

With my device the tube 10 is filled with 'ink .nearly up to the collar 14, and this is retained'by a plug 21 having threads 22 which screw into the threads 11 and a conical end 23 which engages the internally tapered collar 14. If desired, a clip 24 may be .secured to this plug so that the tube may bemore readily carried in the pocket.

When the user finds that the supply of ink in his pen is 'running low, he removesthe plug 21 from the tube, inserts the point of the fountain pen in the tube, and raises the lever 16 to dotted line position and screws the fountain pen' down against the collarv14. This is done with the tube 10 held in an upright position. The pen and tube are now inverted so that when the lever 16 is again depressed to the full line' position ink will fiow into the tube 20 due to the suction therein and assisted by gravity.

I prefer to make the tube 10 of a transparent or at least a translucent -material so that the user can see how much ink flows into the pen and when the iow has ceased. When this occurs, the tube is again turned to its original upright position and the fountain pen removed and the plug l21 replaced.

This permits the user to carry with him a. supply of ink and insures that the quality of his ink will always be uniform thereby preventing a great deal of bother resulting from deposits formed due to mixtures of various kinds ofinks.

The form shown is one in which aspecial tube is designed to be used with a dparticular form of pen having screw threa s 12 at a fairly definite distance from the end 15. In Fig. 3 is shown a modified form of the de- Vice in which the tube 10 is made large enough to admit the ends of a number of sizes of fountain pens which, however, engage only taperedcollar .14 and are held against it during the filling operation by hand. The operation of the device is otherwise the same as previously described.

While I have shown anddescribed but a few embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as possible in view of the prior art.

What I regard as new and desire to secure by Letters Patent, is:

1. A filler adapted to fill the barrels of fountain pens comprising a hollow tube to contain ink and open at one end, and a hollow tapered downwardly converging collar in said tube adjacent its open end and adapted to loe closed by the end of the barrel of the pen so that when the hollow ink-containing tube is inverted the ink therein will be fed to said barrel, s ad tube having threads thereon engaging threade on the end of said .barrel and to hold the end thereof against .said collar,

and a pluo 4for closing said tube. p

2. A filer for use with fountain pens which are illed through the end of the barrel comprising a hollow tube adapted to contain ink rand open at one end, and a hollow tapered downwardly converging vcollar in said end Haring outwardly and adapted to be closed by the end of the barrel so that when the filler is inverted, ink therein may be fed to said barrel, said tube and barrel being provided with coma hollow tapered downwardlyconverging inseam collar in said end Haring outwardly and adapted to barrel so that when the filler is inverted, ink therein may be fed to said barrel, said tube and barrel being provided with complementary threads adapted to hold the end of said barrel against said hollow tapered collar, vand a plug threaded to engage said tube and adapted lto engage said tapered collar to close the tube.

4. As a new article of manufacture, a filler for fountain pens consisting of a tubular member closed at one end, means for securing a. closure at the opposite end of the member.I said'tubular member being provided adjacent its ope-n end with a tapered, downwardly Vinclined collar to form a seat for such closure and for the end ofv a fountain pen in the filling of the barrel thereof, upon removal of said closure.
